So I was driving to work barely made it down the road without smoke in cabin (from heat its cold out!) and eventually saw it from under the hood. Stopped and looked its wet all the way from the valve cover down. Replaced it earlier and no more leak/smoke BUT noticed yellow sludge in air box vent into valve cover. Took the airbox out and found the reason I think the valve cover gasket blew out. Can I just clean this all out and move on with life or!?
